MIXING DEVICE.

Specification of Letters Patent.

Patented' March 12, 1907.

Application filed April 3, 1906. Serial No. 309,606.

oughly mixing and intercommingling various.

materials and commoditiesdsuch, for instance, as teas, ground coffees,or different kinds of fiours or meals.

An object of the invention is to provide a means which is not onlyeffective for the most complete and thorough mixing of the materials,but enables the accomplishment thereof without the necessity of thehands coming in contact with the material which is mixed.

As an example of the availability of the device made in accordance withthis invention, it will be mentioned that in tea-stores it is a commonpractice for the clerk at the time 0l selling mixed teas to place aportion of two kinds of tea in the scoop or receiver of theweighing-scale and to then with the hands effect the mixing before thetea 1s packaged and delivered. This custom is in many cases obnoxious,owing to the uncleanliness of the hands of the salesman, and thereforeby the use of the present mixer the tea of di`erent kinds placed andweighed in the scale is poured from the latter through my mixer, whichalso advantageously serves as a funnel for directing the material into abag and is seen by the purchaser to come to him free from possiblepollution.

The invention consists in a device having the parts in combination andarrangement hereinafter fully described, and set forth in the claims.

In the drawings, Figure l is a central vertical sectional view throughthe mixer. Fig. 2 is a plan view as seen below the section-line 2 2,Fig. l. Fig. 3 is a perspective view showing details of constructionhereinafter particularly referred to, and Fig. 4 is a plan view of aform of blank from which one of the blades of the mixer is made.

Similar characters of reference indicate corresponding parts in all orthe views.

In the drawings, Arepresents an axiallyvertical casing of cylindricalform having a flaring top portion a and a lower end delivery portion b,which is contracted or of decreased diameter.

This mixer, as shown, is supported on a frame B, which may practicallybe composed of wire, including opposite side u rights having in theupper portions thereo' the sockets or bearings b for trunnions d,provided at opposite sides of the casing A.

f f represent blades in series at different levels supported by andextended both downwardly and inwardly from the wall of the inclosingcasing, and the blades of a given tier are inclined, as to their widths,reversing relatively to the cross-sectional inclination of the blades ofthe tier next therebelow. rIhe blades in their inward and downward extensions are preferably non-radial relatively to the axis of the casing,but are extended inlines tangential to an imaginary circle somewhatoutside of the casing-axis. 'Ihe manner of the inward, the downward, andthe transversal extensions and inclinations of the blades and thereversal of the relations of those ol' one tier relatively to the otherwill be clearly understood from the drawings, it being stated,

, however, that in the present drawings for the purpose of clearnessalesser number of blades are indicated than are actually usually used inthe device.

C and D represent conical deectors, the one, C, being shown as locatedwithin the top portion of the casing, while the one D, has its locationin the lower portion of the casing and below the lowest tier ofdeflector-blades. One of the conical deflect'ors is represented as madeunitary with and rotatable in unison with a series of revolubledeflector-blades f2, I

mounted on and revoluble about an axiallyvertical shaft or bearing g. Inthe present instance the combined gate D and revoluble deflector-bladesf2 are represented as located in the lower part of the mixer-casing,while the cone C is represented as immovably supported; but therelations of these parts C and D fl may be reversed, or a conicaldeflector combined with revoluble deflector-blades like those f2 may bemounted in the top portion of the casing in a similar manner to thepartsy rotatably mounted in the lower portion ofthe ICO ing inclined asto their Widths reversely relatively to the cross-sectional inclinationof the blades of the next series.

7. in a mixing device an axially-vertical cylindrical shell or casingopen at top and bottoni, having removably fitted and engaged therewithina plurality of separate and independently-movable ring-sections oneabove another, each ring-section supporting a series of blades inwardlyextended therefrom, several of the blades being as to their widthsinclined downwardly reversely relatively to the transverse inclinationof other of the blades.

S. In a device of the character described, a cylindrical casing open attop and bottom, a plurality of' ring-sections itted and coniined atdiilerent heights therewithin and each face of the ring-section, andinclined as to their widths, the inclinations of one set of the bladesbeing reversed from those ofthe next set.
